mini coil 4''-scope 1220xd-b prototype

hi
this is my working prototype coil for c-scope 1220xd- b

Very nice! How does it work? Where would you use such a tiny coil?

This coil is designed for a research surface in soils heavily contaminated by ferrous objects typical of the military camps of World War I
has a very good discrimination

Hi can you please explane what the oscilloscope is showing?

hi
red signal tx = 17KHz 6.5 volts amplitude
signal yellow = RX coil
the signal on the coil rx original 4'' c.scope is 10-20mV

Hi thanks for the reply could you tell me what it would look like if you had a bad coil.

Just trying to figure out what to look for when i make a mono coil?

my circuit is built with two coils one tx and one rx (4bcoil)
the circuit uses one single coil tx (red wire), the black wire (-TX) is not used and is connected to ground as in the original coil 4'' c.scope (the original coil c.scope is a coaxial type)

the signal rx must be calibrated in resonance so as to be in phase with signal tx
if the coil is calibrated wrong, eliminates some materials

Ah yes, I understand now! thank you for your help, it makes a bit more sense now

the signal must be calibrated to zero volts in phase with the signal tx in resonance, then must be moved to -90 degrees, it is not easy, c.scope normally uses two TX and then with the trimmer modulates the voltage between the two windings in TX this makes it very simple to calibrate the phase of the RX

i m only working on iron infested area(the Thames river) i just bought a 4" king cobra coil and i want to try it on a cibola but i need a new connector
